A new approach to interpreting late Pleistocene microlith industries in southwest Asia

Archaeologists have long assumed that morphological variability in microliths primarily reflects cultural differences among the makers. This forms the basis for differentiating major cultural/temporal traditions in the late Epipalaeolithic of southwest Asia. An alternative explanation for morphological variability is proposed which emphasizes the dynamic aspects of lithic technology in hunter-gatherer societies and questions current explanations of culture change.
